“…Furthermore, the concentration of trace metals such as Na, Zn, Cu, K, Ca, Al and Ti observed in three fish species of our present study were also differs from the findings of previous workers 35 – 44 , who reported these metals in same fish species collected from the Pakistan, India, Oman and Nigerian coastal areas as presented in Table 12 , respectively. Such comparison of trace metal concentrations in these fish species from different studies provides valuable insights into the potential variations in metal accumulation patterns among fish populations in the different locations.…”

Trace metals are naturally occurring metals found in very small concentrations in the environment. In the context of fish flesh, metals such as copper, calcium, potassium, sodium, zinc, iron, and manganese are absorbed by fish and play vital roles in various physiological functions. However, if these metals exceed the recommended limits set by WHO/FAO, they are termed 'toxic metals' due to their harmful impacts on both the fish and its consumers. Therefore, the present study aims to analyze the levels of protein, lipids, and certain metals—Aluminum (Al), Sodium (Na), Zinc (Zn), Titanium (Ti), Iron (Fe), Copper (Cu), Potassium (K), and Calcium (Ca) in three commercially important marine fishes i.e. Rastrelliger kanagurta, Sardinella abella, and Otolithes ruber. The study also aims to assess their potential impact on human health. The macro-Kjeldhal method and Soxhlet apparatus were used to estimate protein and lipid contents, while atomic absorption spectroscopy (AAS) was used to estimate trace metals found in fishes. The study found that these fish species are valuable sources of protein, lipids, and certain essential minerals. The protein content (CP) in these three species ranged from 63.35 to 86.57%, while lipid content was from 21.05 to 23.86%. The overall results of the trace metal concentrations analyzed in the present study revealed that Aluminum (Al), Sodium (Na), Zinc (Zn), Titanium (Ti), Copper (Cu), Potassium (K), and Calcium (Ca) were found in low concentration or traces and also within suitable ranges as set by WHO/FAO. However, Iron (Fe) was absent in all three species. Moreover, both copper and potassium were found in all three species, while Zinc was present in Rastrelliger kanagurta and Sardinella abella, calcium in Sardinella abella, and sodium in Otolithes ruber only. Titanium was recorded for the first time in S. abella. However, the total health risk assessment associated with these fish food consumption was measured by THQ and TTHQ and found to be less than 1, which shows no potential risk related to trace metals found in these fishes on human health upon their consumption. In conclusion, these commercially important marine fish species were found valuable sources of protein, lipids, and essential trace minerals that are necessary for human health. Thus, the current study provides useful information for the local population to make informed decisions about their daily diets and highlights the importance of sustainable fishing practices to maintain these valuable marine resources by periodical monitoring of their ecosystem.

Fish is an important source of protein in human meals around the world. However, the fish that we are eating may be contaminated with toxicants such as metals and metalloids (MMs), which may pose health risks to consumers. Information on MMs content in fishes and their potential spatial distribution scenarios would provide knowledge to the community to create strategies and protect human health. Hence, this study assessed and determined the health risk levels of MMs in both brackish and marine water fish (BMF) in Puerto Princesa City (PPC), Palawan Province, Philippines. PPC has an existing abandoned open mine pit near the PPC coastline called the “pit lake”. The concentrations of As, Ba, Cu, Fe, Mn, Hg, and Zn in fishes were analyzed using portable Olympus Vanta X-ray Fluorescence (pXRF), and the spatial distribution of MMs concentrations in BMF was analyzed using a GIS (geographic information system). Fishes were sampled from fishing boat landing sites and nearby seafood markets. The results revealed that the concentration of MMs in marine fish was generally higher than the brackish water fish. It was recorded that the Hg concentration in marine water fish meat was higher than in brackish water fish meat. The Mn concentration in marine water fish exceeded the permissible limits set by international bodies. An elevated concentration of Mn in BMF was detected across the northern part of PPC, and an elevated concentration of Hg in marine fishes was recorded in the southeast area, where the fish landing sites are located. Ba was also detected in BMF across the southern part of PPC. Moreover, an elevated concentration of Cu was detected in MBF in the northeast and in marine fish in the southeastern area of PPC. Further, this paper elaborates the non-carcinogenic and carcinogenic risks of these fishes to the PPC population and tourists with respect to the MMs content in fish meat.

“…However, this needs to be consistently monitored as the HQ value is nearly 1. Moreover, Mangalagiri et al (2020) reported that the accumulation of Pb in Rastrelliger kanagurta from India was higher than the limit set by the Joint FAO/WHO (2004) Expert Committee on Food Additives (JECFA, 2003).…”

“…This indicates that the pollution status in the Malaysian coastal environment may be moderate to high and needs to be monitored. In India, the concentration of Pb is on the borderline due to Rastrelliger kanagurta that was harvested along the coast of Visakhapatnam has been recognised as a high industrial area (Mangalagiri et al, 2020). In Malaysia, the concentration of heavy metals increases may be due to marine pollution and activities, such as cross-channel shipping, transit traffic, and fishing activities (Khandaker et al, 2015).…”

Global aquatic ecosystems are becoming increasingly polluted with heavy metals posing health concerns associated with fish consumption. This study aims to determine the concentrations of cadmium (Cd) and lead (Pb) in local and imported fish (Rastrelliger kanagurta), and its potential human health risk. Total local and imported fish (60 samples) were randomly selected and purchased from ten different supermarkets in Shah Alam, Selangor. Cd and Pb concentrations were assessed by using dry ashing-acid digestion technique and analysed with atomic absorption spectrometry (AAS). The analytical results shows that the mean concentration of Cd in local and imported fish (Rastrelliger kanagurta) were 0.487 ± 0.25 mg/kg and 0.267 ± 0.11 mg/kg, respectively. The mean concentration of Pb in local fish was higher at 2.774 ± 1.46 mg/kg compared to the imported fish (1.482 ± 0.81 mg/kg). Further analysis indicated that there are significant differences (p < 0.05) for both Cd and Pb levels in local and imported fish (Rastrelliger kanagurta) sold within Selangor supermarkets. The concentration of Pb in local fish sold from supermarkets failed to comply with all the standards guidelines. The hazard quotient (HQ) used for health risk assessment of Pb and Cd was found to be < 1 (HQ < 1) for imported fish and potential risk for local fish (HQ > 1). The study reveals that the local fish are not totally safe for consumption and the pollution concentrations are on the borderline but can be treated.
